Do you already have a Google Home Mini or any smart speaker in your closet? Congratulations, you already have a sound machine capable of white noise, and much more. A simple command, like “Hey Google, help me relax” will trigger 12 hours of ambient noise (if you don’t stop it). You can also say “play rain sounds,” fireplace sounds, country night sounds, or babbling brook sounds. Google speakers let you create a bedtime Routine, as well (learn more about Routines). These features work on any Google Speaker. You can also search for and play white-noise playlists on Spotify or other music services.
